Genetic basis

Extension e/e, Pearl nPrl — the Pearl gene (MATP) dilutes differently from Cream on a chestnut base.

The Dun gene dilutes the base coat and adds primitive wild-horse markings: a dorsal stripe along the spine, leg barring, and sometimes shoulder stripes.

The Frame Overo pattern adds irregular white patches to the base coat. Crossing two Frame horses is dangerous: 25% of foals will be homozygous O/O (OLWS) and will not survive.
